[Q] Network or software problem? - Galaxy S III Q&A, Help & Troubleshooting

Whenever I tried to on my mobile data in 2G mode in certain areas it never opens or took too long to start but it's fine again in 3G mode. Is this network related issue or Software problem? Your help will be highly appreciated.

Should be a network problem…… never heard that 2g module can be broken when 3g is still working……

[Q] 3G-2G switch data problem

I experienced this problem with two X10, when you are on WCDMA only mode and data connection is active, try switching to GSM mode only. Your data connection will not restore until you enable then disable Airplane mode.
Anyone having this same problem? Both X10 have different manufacturing date and tried it also with different provider but same results
Mine doesn't do that. I do this all the time when I don't want to get over my limit in one day which is 1GB of data...
Mine does the same thing. I have no problem switching from 2g to 3g. But when I go back from to 3g to 2g I have to turn on airplane mode to enable data again. I am running GB 2.3.3 JVB. But the same thing happened on 2.2.1. Being searching like crazy and havent found any solution. Anybody know how to fix this? Maybe its a network problem not a phone problem.
Hi there.
I have the same problem. Do you have any news?

Airtel Mumbai users, is the network acting up?

I had absolutely *no* issues with the cellular network whatsoever until yesterday noon, that's when the problems started, all of a sudden.
I started experiencing disconnections from the 3G network intermittently, like every 5-10 seconds it would disconnect and reconnect, extremely unstable. I then put the phone in 2G mode, but I lost my EDGE data connection despite the APN's configured properly. I even called up the provider and had them deliver the APN settings to the phone, but to no avail. My data connection just didn't work, i.e. no 'E' symbol, nada,
Thinking it might be something to do with the ROM, I restored my 2.1 backup via xRecovery, but experienced the exact same issues. Extremely unstable 3G with it's intermittent disconnects etc and NO data connection when it 2G mode. In the 'About Phone' status, it just shows 'Unknown' as the mobile connection type and 'disconnected' in the connection state.
I even went ahead clean flashed the 2.1 .435 ftf via flashtool, but the same issues persist!
What do you think the problem could be? I triple checked with my operator and they say the data services are active on my number, no problem from their end.
Could it be a hardware issue? I unfortunately don't have another SIM I can test with - that said I greatly doubt it could be a hardware issue.
What do you think?
I'm on Wolfbreak's CM 6.1.3 v4.4
Could be a network issue. Do you have this problem at a different place. May be in a different cell. There's always issues initially after deployment of new 3g deployment.
There is rarely a problem with only the data part. As all the protocol stack are not changed or fiddled in these new rom.
So less chance of the rom.

Yeah probably a network issue due to the super important india-pakistan semi final.

Data Connection Problem

Hi
I am having problem with my internet (data) connection on my phone.
What's happening is that i start using the internet connection with no problems then at one point i lose data connection - all other serviced work well - sms / calls.
In order to get my data connection back i either have to restart phone or else go to flight mode and off flight mode again.
Is anyone experiencing a similar problem?
Ken
same issue, also with WIFI hotspot as well. really frustrated.
Hi Anyone else having the same issue or not having such an issue?
Since i am still not sure whether this is a phone problem or a service provider issue?
Ken
similar issue here.
i can only conncet to Edge buy setting the network mode to GSM only
using GSM/WCDMA auto results constant switching between H+ and 3g and then the device enters flight mode.
Any idea!!!!!!!!

[Q] WCDMA only mode = no wifi connection

Hello,
In my area I find that I keep jumping from HSDPA to Edge and back constantly, which breaks my data connection briefly. It's very annoying.
I found that changing the setting to WCDMA only fixed this, and did not result in loss of data connection - it just kept me where I needed to be.
Only problem is at my house, suddenly I could not connect to my wireless internet no matter what I tried. I could connect to the neighbors slower open internet connection, but not my own. Tried everything. When I set it back to Auto mode, I could connect again with ease.
Any suggestions for a way to be WCDMA only and still connect to my wireless? I don't understand networking well enough to help myself.

3G connection on 10.1

Hi..
I just bought a tab 10.1
Somehow the 3G connection is not stable.. it will suddenly be turned off even though mobile data is on..
I checked the apn settings and it is blank.. typed in my own and after awhile it disappears too..
Is this a known issue?
Anyone facing similar issues?
Sent from my Energized HTC Sensation
For some reason my 3G data is not pulling through the tablet either. This is from my Galaxy Prevail
Are we the only two with this issue..
Wonder what is the cause:
Sim card?
Hardware?
Software?
At a lost now..
I have a similar problem. On my unit the H+ is displayed only when there is network activity and when there is no activity it turns to 3G. Problem is that this causes about a second of lag on every click on the link before it turns to H+ and then starts to download the page.
Another problem is that the signal strength display in ASU is suck at 4.
